Departure time will depend on what time my son is going to surface from his flea pit... At the age of 15 that could be after lunch
Seriously, he'll be riding pillion, so I'll have to give him a bit of time, so it'll probably be about 11.
I normally ride up the A308 from Windsor and onto the A404 at Bisham, drop down to the A4130 and on to Henly, so I can meet you anywhere around there if you like...
